[ARC5] [Milsurplus] RAX

[Al Klase]

FWIW,

I have my RAX-1 running at the Radio Technology Museum 
<http://www.rtm.ar88.net/> demonstrating the signals heard by David 
Sarnoff and Ed win Armstrong during Armstrong's demo of his regen 
receiver in late January 19114 at our site, Marconi Balmar, NJ.

See it here: http://www.skywaves.ar88.net/VE-1.mp4

Enjoy,
Al
